What plants can be cloned and can plants be cloned? Can plants be cloned?

--- many kinds of plants can be cloned, the cloning of plants is called "tissue culture", which is generally used to propagate some rare plants or plants with greater economic value, otherwise I am afraid that even the cost of tissue culture will not be recovered, the most common are "phalaenopsis" and "orchids".

1. Rapid propagation of some rare plants or plants with greater economic value.

Relying on natural conditions to propagate rare plants and plants with high economic value in a short period of time is limited by geographical environment and season, and it is difficult to achieve the purpose of fast and efficient. Especially for plants that need to reach a certain number in a short period of time in order to create valuable plants, time is the benefit, and only through the method of tissue culture can this requirement be met.

The propagation of plants by tissue culture is the main and most effective example of the application of tissue culture to production. The first is the successful application on orchids. Since Morel obtained orchid tissue culture seedlings in 1960, they were quickly used in production, forming a tissue culture propagation orchid industry.

Because the obvious feature of tissue culture propagation of plants is that it is fast, and it can reproduce millions of times faster every year, it is of particular significance to the propagation of some famous and excellent plant varieties with low reproduction coefficient and cannot be propagated by seeds.

2. Detoxification. Many plants carry viruses, which seriously affect the yield and quality of plants, and bring disasters to agriculture. In particular, vegetatively propagating plants, such as potatoes, strawberries, garlic, carnations, etc., because the virus is transmitted through vascular bundles, the use of these plant vegetative organs to reproduce will bring the virus to new plant individuals and cause diseases.

However, it has also been shown that not every part of the susceptible plant carries the virus, such as the part of the stem tip where the growth point has not yet differentiated into vascular bundles, which may not carry the virus. If the stem tip culture is cultivated using tissue culture, it is possible to obtain virus-free seedlings for regenerated plants, and then use such seedlings for propagation, so that the planted plants will not or rarely develop viral diseases.

The obtained detoxified vaccine must be identified and confirmed to be virus-free before it can be used. The use of tissue culture to obtain detoxified seedlings has been successful in strawberries, grapes, carnations, etc., and has obvious economic effects.

3. Preservation of plant germplasm resources and rescue of endangered plants.

For a long time, people have thought of many ways to preserve plants, such as storing fruits, storing seeds, storing roots, tubers, bulbs, bulbs; With normal temperature, low temperature, variable temperature, low oxygen, inert gas filling, etc., these methods have received good or relatively good results to a certain extent, but there are still many problems. The main problems are the high cost to pay, the large space occupied, the short storage time and the susceptibility to environmental conditions. Plant tissue culture combined with ultra-low temperature preservation technology can bring a big leap forward to plant germplasm preservation.

Because preserving a cell is equivalent to preserving a seed, but it only takes up 1/10,000 of the original space, and it can be stored for a long time in liquid nitrogen at -193 degrees, unlike seeds, which need to be renewed every year or often.

Except for Dave, you can sell plants.

Such as cactus, sweet potato, willow.

Yes, the wax bush. What you call plant cloning is actually called asexual reproduction in botany. It is abundant in plant production, especially in flower cultivation, such as cuttings, cherry tree propagation, graft propagation, strip propagation and tissue culture are asexual propagation.

The new plants obtained through asexual withering propagation are theoretically genetically identical to those of the mother.

Yes, the answer is yes. Plant cloning is vegetative reproduction, and there are four main ways: rooting, stripping, cuttings, and grafting.

The answer is yes. In fact, long before the successful cloning of animals, humans knew that many plants had this cloning ability. For example, a long time ago, human beings discovered that some plants can reproduce by asexual cuttings by cutting off part of the organs on the plant body under suitable conditions.

The organs of cuttings can be roots, shoots, and leaves, such as wisteria roots, willow branches, begonia leaves, etc. After a period of time, the branches inserted in the soil grow roots at the lower end and buds at the upper end, and gradually grow into the same plant as the parent parent. The plant body is not like an individual animal, it is an open system, integrated into nature with an open attitude.

The aboveground part of the whole plant body passes through the shoot tip, and the underground part passes through the meristem area of the root tip, and under certain conditions, various tissues and organs are repeatedly differentiated and grown, which is completely different from that of animal individuals.

Plant cuttings propagation is achieved through asexual reproduction (cloning) of plant organs, so do plant cells also have such a function? Since the beginning of the 20th century, the concept and technology of plant cell culture have been gradually proposed and developed by scientists. It was not until the 60s of the 20th century that scientists used a single isolated plant cell culture to obtain the regeneration of the whole plant, and completed the real cell cloning process of obtaining the whole plant from the non-germ cells of the plant.

To date, hundreds of plant species of Lianghengyun cells can be cultured and regenerated into whole plants.

Of course, it is possible, plant cloning is easier than ordinary animal cloning, and now that they have made more obvious progress, it is relatively easy to carry out plant closing.

Yes, plant cloning is much more mature than animal cloning, and the maturity rate is much higher. The most typical plant cloning is plant tissue culture Plant cloning said that the popular point is tissue in vitro culture, and then the popular "bubble root" has you ever heard of, the root bubble out is a new or letter individual. Plant clonal phase.

Cloning is the use of somatic cells to reproduce into a complete individual. Therefore, plants can be cloned completely, and the specific tissue culture of plants is a particularly obvious plant cloning operation. A small section of plants can be cultivated into hundreds of base cave barks.

Nowadays, cloning technology is constantly improving, and in order to make the survival rate of plants higher, plants can use cloning technology.

It must be a useful way to draw in the relationship between them, and when the two have exchanged secrets with each other, the distance between them will be much more dense. In fact, your privacy is protected and you are able to defend your privacy.

Cloning plants has the following disadvantages compared to traditional propagation methods:

1.Declining biodiversity: Since cloned plants are all copies of the same genotype, their genetic information is almost identical.

This has a negative impact on the diversity of ecosystems, as genetic differences between species can make them more resilient to different environmental conditions and resistant to infectious diseases.

2.Pest and disease risk: Clones have little genetic change, so they have the same susceptibility or resistance, which means they can be threatened by the same pathological, bacterial, fungal and insect at the same time, leading to potentially catastrophic disease outbreaks.

3.Growth disadvantages: Compared to natural reproduction, many clonal plants exhibit fixed traits during growth, such as smaller root systems, shorter growth heights, etc., which may negatively affect their viability.

4.Lack of adaptability: Due to the lack of genetic variation, cloned plants have very limited adaptability to changes in the external environment. This means that they may be more susceptible to climate change, ecosystem disturbances, and human activities that could lead to their extinction.

Plant cloning technology is the use of vegetative organs of plants for breeding, belongs to the category of asexual fast propagation technology, and is also a seedling technology based on cell totipotency and plant totipotency.

The so-called totipotency of the cell: refers to the DNA genes contained in the plant cells, which can replicate the same genetic traits as the mother under suitable conditions.

It means that the branches, leaves, buds and other parts of the organs or tissues of the plant contain all the information of the whole plant. So, can all holographic and totipotent vegetative organs develop into a complete individual regardless of conditions? It must be under suitable conditions, in order to develop into a complete plant, like leaves, in a suitable habitat, in order to grow a lot of seedlings, each seedling is the same in the information, so that the cell totipotency and the holographic nature of the plant is the internal cause and fundamental of the plant to achieve fast reproduction, they are inseparable from the role of external factors, that is, suitable conditions, in the process of fast reproduction, this suitable condition is provided by computer intelligent control technology, temperature, light, gas, people, nutrition, hormones and other habitats are optimized, Then the expression of the holographic totipotency of the in vitro material will be faster, so as to achieve rapid seedling.

Cloning technology is a comprehensive technology combining rapid seedling technology and multi-generation circulation technology, in the computer-controlled intelligent environment, coupled with the artificial supplement of nutrient solution and hormones, so that the plant in vitro material can quickly become seedlings, but if it is not combined with multi-generation circulation technology, it can not achieve high-speed multiplication. An isolated material can only become a small seedling, and if multi-generation recycling technology is adopted, (also called seedling propagation) can achieve a geometric doubling of seedling production. This is of great significance for some rare plants and plants with a large number of seedlings in production.

For example, returning farmland to forest, a large number of forestry seedlings, forestry, agricultural industrial development, etc., to provide a large number of seedlings for production, the use of multi-generation recycling technology, annual rapid multiplication, can make an isolated material in one year to achieve geometric value-added.

According to the theory of Ma Jinhai, an expert in fast plant reproduction in Jiangsu, cloning is also asexual reproduction, and in this sense, all plants can now achieve asexual reproduction, that is, plants can be cloned.

Methods of cloning:

1. IVF tissue culture.

2. Cuttings or most plants can be sprayed with plant shoots summarized by Ma Jinhai's 18 years of practice to multiply quickly. Auxiliary equipment is automatically controlled, such as the automatic control of light-sensitive nursery machines.

Cell totipotency: Plant cells contain DNA genes that can replicate the same genetic traits as the mother under the right conditions.

Holographic nature of plants: The branches, leaves, buds and other organs or tissues of the plant contain all the information of the whole plant.

You can meet both of these conditions.

Clone.. Is this the following?

You mean plants clone themselves???

Plants can basically clone, and the totipotency of cells is based on plants.

As for which plants will clone, your question is interesting. Do you want to ask what are the plants that are mainly cloned now? Or something else?

There is ambiguity in the question. At present, grain crops, oil crops, fruits, vegetables, etc., because of the need to carry out transgenic research, one of the links is cloning, so rice, wheat, corn, citrus, apples, rape, potatoes, etc.

Wicker, potato, cactus.

Most plants are fine, and many plants in horticulture are propagated by cuttings, and in the case of animals, only low-level animals can be used.

Example 1: "Dolly" sheep: In August 1996, scientists extracted somatic cells from a black-faced sheep, and then injected the nucleus of this somatic cell into the egg cell of another white sheep, and the egg cell had been removed from the nucleus, and finally the newly synthesized egg cell developed in the womb of the third black-faced sheep to form Dolly sheep.

Theoretically, Dolly inherited the genetic traits of the sheep that provided the somatic cells. The technique of breeding Dolly sheep has become the standard process for breeding somatic cloned animals today.

Example 2: The stem of a strawberry is creeping on the ground, and every time it grows, it will produce whisker-like roots that automatically burrow into the soil, and then cut off the stem to form a new plant.

Example 3: Mushrooms reproduce by spores emitted into the air, and the spores will grow when they attach to a suitable environment.

Bamboo, reed, and lotus have well-developed rhizomes, and side buds grow from the axils of the scaly leaves of the rhizomes, and then grow from the side buds into leaves with long stalks, and many adventitious roots grow at the base of the petioles. Each rhizome grows many new aboveground plant bodies each year.

Example 4: A willow tree can grow into a willow tree by breaking off its branches.

Plant cloning is vegetative propagation.

There are four main ways.

Divide the root one. Split roots: used for oleander, plum and other shrubs, their clumping stems each have roots, can directly separate them into independent plants. This type of reproduction is called root splitting.

Bead two. Striping: For mulberry, oleander and other plants, you can choose the longer branches on the tree, bend it down, and after the branches buried in the soil grow roots, then cut off the branches from the parent body to grow into new plants. This method is called a bead.

Cuttings three. Cuttings: Used for plants such as moon, willow, grapes, etc., you can cut the budding branches on the plant and insert them into the soil, and soon these branches will take root and sprout and grow into new plants. This method is called cuttings.

Graft four. Grafting: Used in fruit trees such as oranges and peaches, their branches or buds can be attached to the stems or roots of another plant, so that the cambium layer of the two (the tissue with meristem in the stem) is close together, and soon they will grow into one and become a new plant.

This method of reproduction is called grafting.
